Lactic acid bacteria were isolated from pig feces for probiotics. The six isolated strains were identified as Lactobacillus paracasei (Lp), Lactobacillus fermentum (Lf), Lactobacillus brevis (Lb), Lactobacillus plantarum (P1, P2), and Pediococcus pentosaceus (P3) by its sugar utilization, morphological and physiological characteristics. P1 was showed largest antibacterial
inhibition zone among the isolated strains. It was against Salmonella gallinarum 25 mm, E. coli 20.5 mm, Staphylococcus aures 24 mm, and Pseudomonas aeruginosa 28 mm by inhibitory zone, respectively. Lf was showed hyper acid tolerance, 80% survival rate for 40 minutes, and P1, Lb showed hyper bile tolerance, 408%, 283% survival rate for 9 hrs, respectively. Therefore the Lf, P1, and P2 strains were expected to probiotics.
